Weird and wonderful DIY holidays – Technically, on Japan's Greenery Day (May 4), locals are meant to get out in nature. Really, though, it's an excuse for a day off.

It was moved to May 4 and became more orientated around nature (apparently, the emperor was a fan of the outdoors).

Story highlights

Thomas Roy has created over 90 holidays, all of which he's trademarked.

Roy's most popular celebration is Northern Hemisphere Hoodie-Hoo Day.

Anyone can create a holiday by sending a form to Chase's Calendar of Events.

Hallmark recently started commemorating Star Wars Day with e-cards.

It used to be that an event had to be truly momentous to warrant a new holiday -- be it the birth of a prophet or a hard-won battle for statehood. But these days all that's needed to craft a commemorative day is good dose of ingenuity and a marketing plan.

Indeed, one man alone is probably responsible for most of the world's more ridiculous holidays. American Thomas Roy has invented -- and copyrighted -- over 90 holidays in the last 26 years, including No Socks Day (May 8) and Married to a Scorpio Support Day (November 18).

But when he first started brainstorming silly things to celebrate, he had no idea that some of his inventions would one day make it onto calendars and diaries. He certainly didn't imagine that anyone would observe them.

"I just started doing it on a lark," admits Roy, who used to flip through Chase's Calendar of Events -- an annual reference guide to holidays around the world -- to get ideas for the morning radio show he hosted out of Lebanon, Pennsylvania. One year, he noticed a form in the back of the book inviting readers to submit their own holidays.

Beginner's luck – For the first few weeks in July, night skies on both sides of the Atlantic are lit up by spectacular fireworks -- from America's 4th July to Bastille Day in France, with a host of international fireworks competitions in between. To honor this pyrotechnic frenzy, we asked you to send us some of your sparkiest fireworks shots from across the world.

Marcia Taylor's day job, as a British Airways' cabin crew member, takes her all over the world -- but the 27-year-old never travels anywhere without her camera. Believe it or not but this was her first time shooting fireworks. She traveled to Paris especially for the fireworks on Bastille Day last year.

"It was a disco theme, the music started and as soon as the fireworks began the crowd had a fantastic atmosphere, every single person was on their feet singing along not taking their eyes of the fireworks," she says.

A revolutionary tale – Photographer Martin Castellan, 62, took this color cascading photo of the Bastille Day fireworks in the city of Carcassonne in the south of France. Bastille Day is celebrated on July 14 and commemorates the storming of the Bastille prison in Paris in 1789 -- an event which triggered the French Revolution.

Mr Castellan says the city's 11th century castle was built by the Cathars, a Christian sect seeking protection from the Pope's armies, and in 1991 it doubled for Nottingham in Kevin Costner's Robin Hood - Prince of Thieves film.

The background music made it so much more special. Seeing these fireworks made me feel like I was in a fantasy world in a fairy tale," says the 33-year-old computer software developer.

London lights up – Kenneth Ngyuwai celebrated the first moments of 2013 in London where he snapped the crescendo of the New Year's Eve fireworks display on the river Thames.

"Fireworks never fail to amaze me. One might say that everything there is to a firework is just a can of chemicals that produces bright light when exploded in mid-air. However, when choreographed properly as in this case with the London Eye, it creates a spectacular once-in-a-lifetime show that everyone can enjoy and talk about with their friends for years to come," he says.

For this year's Fourth of July he was determined to get a super snap of Macy's firework display in New York City.

To him the most special thing about Fourth of July is seeing America come together to celebrate its history.

A fortnight of fireworks – Photographer Edmund Lowe captured this stunning photo of the fireworks over Legoe Bay, Lummi Island in Washington State on the Fourth of July in 2011. "Fireworks make adults turn into kids again," he says. He also has some great tips for those wanting to capture iconic fireworks shots:

"The main requirement is a tripod, I use a sandbag or some other heavy object to make sure there is no tripod shake. Long exposures, up to ten seconds are required. I generally use an f-stop of f/11 to f/16 and a shutter speed of two-ten seconds. The longer exposures will also give you time for multiple reports to be visible. This fills the sky with the sparkles."

"It was spectacular for a multitude of reasons. To begin, it was a military celebration that opened with the German and American National Anthems. Just the opening itself set the stage for what my family and I thought were one of the most patriotic and spectacular firework displays that we have ever had the pleasure to see. The display lasted for at least 30 minutes of non-stop fireworks," said the 31-year-old who is originally from Belle Glade, Florida.

"I was like, 'oh no, don't tell me this is possible,'" he recalls. For fun, he crafted Northern Hemisphere Hoodie-Hoo Day -- Roy's answer to curing cabin fever. On February 20, observers are meant to hit the streets at noon and shout, "hoodie hoo". To his surprise, the holiday was printed in the next edition. It wasn't long before various media got a hold of it and started promoting the day as a fun, off-the-wall thing to do.

Shortly afterward, the letters started coming in. Roy received invitations to Hoodie-Hoo Day celebrations. Occasionally, corporations pay him to use some of his creations. A few years ago, Entenmann's Bakery used his Eat What You Want Day in one of their ad campaigns.

"It was kind of scary," he says. "This is how politicians get into office with these nonsensical ideas, and people buy into it."

In 1985, Australian Elaine Fremont wanted an excuse to have a monthly party. She invented Bonza Bottler Day, which she celebrated on any day that matched the month (i.e, January 1, February 2 ... ). Though Fremont passed away in 1995, her sister, Gail, carried on the tradition, and the holiday has achieved a cult status in Australia.

Official holidays don't always follow logic, either. Japan has a law that states that when two holidays fall with a day between them, the middle day becomes a de facto holiday. According to Kylie Clark, a spokesperson for the Japan National Tourism Organization, it's recognized that some holidays are mainly an excuse for the populace to take time off.

"Japanese people tend to be hesitant to use their annual leave," she admits.

In recent years, bolstering awareness has been another popular reason to craft a celebration. Though special interest groups often spearhead these initiatives, sometimes a day is granted importance just because a particularly enthusiastic individual thinks it should be.

Keith Milsom could be one of the most dedicated lefties in the world. He runs an online shop -- founded as a brick-and-mortar storefront in Central London by his left-handed father in 1967 -- called Anything Left-Handed. Though hard to prove, he strongly suspects Simpsons creator Matt Groening -- himself a leftie -- used the store as his basis for Ned Flanders' shop, The Leftorium.

Several years ago, Milsom founded The Left-Handers Club, and shortly started receiving queries about starting a holiday to support left-handed people. He launched International Left-Handers' Day on August 13, 1992. The date was picked to coincide with a slow news cycle so that it would have a better shot at garnering some media attention.

"250,000 people visited our site on the day last year. Unfortunately, that doesn't always convert into orders," says Milsom. "While there's a lot of interest in left-handed products, there's also a lot of apathy."

Still, he's been contacted by dozens of people who have concocted their own Left-Handers' Day celebrations.

"It tends to be people converting their spaces in to 'lefty-only' zones. We've heard of people who own pubs and make a rule where everyone has to drink with their left hand that day. It's fairly low-key," he admits.

Ultimately, though, the true test of a holiday's validity is if it gets its own greeting card. While Hallmark denies creating holidays, the company says it employs a team of 600 to research events worth celebrating. While Hallmark isn't making Hoodie-Hoo Day cards yet, this year it started making Star Wars Day e-cards.

"We've seen the demand for that rise out of social media," says Hallmark spokesperson Kristi Ernsting, who adds that customers were creating their own "May the Fourth Be With You" e-cards through the Hallmark site. The company decided to follow suit.
